Tutors can sign up for Priority Hours a maximum of three weeks in advance. If Priority Hours are very popular at a given time, they might simply not be available in that window. Tutors tend to drop Priority Hours up to 12 hrs before though, so we recommend checking back often. Priority Hours tend to open up as the time approaches.
The three-week horizon is adjusted based on your tutor rating.
The best way to improve Priority Hour access is to impress students!
If a tutor has a low tutor rating, we encourage them to pick up Priority Hours that are currently available, perform well on them, and then see their rating improve (and Priority Hour access along with it).
